A regularized nonlinear diffusion approach for texture image denoising
(2009-12-01)
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...

An anisotropic a priori error analysis for a convection-dominated diffusion problem using the HDG method
(Elsevier Science SA, 2019-03-01)
This paper deals with the a priori error analysis for a convection-dominated diffusion 2D problem, when applying the HDG method on a family of anisotropic triangulations. It is known that in this case, boundary or interior ...
Combining anisotropic diffusion, transport equation and texture synthesis for inpainting textured images
(2014-01-01)
In this work we propose a new image inpainting technique that combines texture synthesis, anisotropic diffusion, transport equation and a new sampling mechanism designed to alleviate the computational burden of the inpainting ...
Modal analysis of anisotropic diffused-channel waveguide by a scalar finite element method
(Institute of Electrical and Electronics Engineers (IEEE), 1998-09-01)
A procedure to model optical diffused-channel waveguides is presented in this work. The dielectric waveguides present anisotropic refractive indexes which are calculated from the proton concentration. The proton concentration ...

The Canny detector with edge region focusing using an anisotropic diffusion process
(2006-12-01)
This paper proposes a methodology for edge detection in digital images using the Canny detector, but associated with a priori edge structure focusing by a nonlinear anisotropic diffusion via the partial differential equation ...
